The disclosure describes assemblies, systems, and techniques for reinforcing complex geometries of pressure vessels using a pre-sintered preform (PSP) braze material that includes a low-melt powder and a high-melt powder. An example technique includes positioning a PSP reinforcement on a surface of a substrate. The technique includes heating the PSP reinforcement to soften or melt at least one constituent metal or alloy of the low-melt powder. During heating, the PSP reinforcement is configured to conform to a contour of the surface of the substrate. The technique also includes cooling the PSP reinforcement to define a reinforced component.

An apparatus for manufacturing a mask is provided. The apparatus includes a stage on which a pre-mask is disposed, and a laser irradiation device including a laser generation member, an optical system for controlling a shape of a laser beam, and a scanner for adjusting a path of a laser beam that has the shape controlled by the optical system. The pre-mask includes a first pattern groove defined on a front surface and a second pattern groove defined on a rear surface that corresponds to the front surface. A first portion and a second portion are defined in a first direction that is a thickness direction of the pre-mask. The laser beam with the controlled shape is irradiated to the second portion of the pre-mask in a second direction crossing the first direction, a mask having an opening, in which the second portion is removed, is provided.

A welding apparatus radiates a laser beam to a welding position in a state where a focal spot of the laser beam is in a near-focusing state. The welding apparatus radiates the laser beam to the welding position in a state where the focal spot of the laser beam is in a far-focusing state. The welding apparatus radiates the laser beam to the welding position in the state where the focal spot of the laser beam is in the far-focusing state. The welding apparatus radiates the laser beam to the welding position in a state where the focal spot of the laser beam is in the near-focusing state.

Provided is a rapid manufacturing process of ferrous and non-ferrous parts using a plasma electron beam in which the plasma electron beam is workable even in a low vacuum pressure environment and has a relatively large radiation range, productivity of the process is improved as a high-power beam can be emitted to a ferrous and non-ferrous powder, and production costs are reduced due to low maintenance and manufacturing costs.

This application concerns a magnet having a magnet body as well as a method for manufacturing such a magnet. The magnet body has a first region with first magnetic properties and a second region with second magnetic properties that are different to the first properties. Owing to the manufacturing process of the magnet body, the relative location of the first region and the second region within the magnet body is freely predeterminable.

A golf club head includes a heel portion, a toe portion, a hosel, and a striking face. The striking face includes a plurality of scorelines each having an average depth no less than about 0.10 mm, a plurality of micro-grooves each having an average depth no greater than about 0.010 mm, and a plurality of textured surface treatment regions superimposed on the micro-grooves so as to at least partially intersect the micro-grooves.

An article, for example a turbomachinery article is presented. The article includes a weldable first component having a base portion and a flange portion. The flange portion is outwardly projecting normal to a surface of the base portion; and is joined with the base portion by a solid state joint. The base portion comprises a nanostructured ferritic alloy; and the flange portion comprises a steel substantially free of oxide nanofeatures. The first component is joined to a second component through the flange portion of the first component by a weld joint.

A manufacturing process includes additive manufacturing a component; and precipitating carbides at grain boundaries of the component.

A method of manufacturing a deposition mask includes: a splitting process in which a laser beam irradiated from a light source is split into a plurality of laser beams; a scanning process in which the plurality of laser beams are simultaneously scanned onto the mask substrate; and a tuning process in which irradiation states of the plurality of laser beams are finely changed to correspond to shapes of the plurality of pattern holes while the plurality of laser beams are scanned.

A method of forming a metal component having different regions containing different grain sizes and in porosities is by additive manufacturing. The method includes spreading a layer of starting powder on a temperature controlled moveable platform in a heated chamber with atmosphere and temperature control. Selected areas of the powder are melted and solidified with a computer controlled focused energy beam. The cooled platform is then indexed down and the process repeated. The grain size of the melted and solidified region can be controlled by the cooling rate during solidification which, in turn is controlled by the temperature of the chamber and the temperature of the cooled moveable platform.
